Patent-pending 24k gold-keratin peptide complex technology works like a magnet to attract and bind keratin to hair fibers to rebuild and strengthen the hair without weighing it down. Heat-activated protein and topical keratin help repair, protect and condition. Biotin, pro-vitamin B5 and shea butter penetrate deep into each hair fiber to help condition and nourish hair. It rinses out weightlessly so that your hair comes to life as moisture is replenished and strength is renewed for shiny, voluminous, silky-soft, lustrous strands.How to use: After shampooing, apply a generous amount to your entire head from the roots to the ends of towel-dried or damp hair. Cover with a shower cap. Place the signature included bonnet over your hair and pull the drawstring to secure. Fasten the adjustable chin strap to hold the bonnet in place. Attach the elastic tube securely over your hair dryer nozzle and turn it on using a low setting only. Run your hair dryer for 15-30 minutes. Remove the bonnet and dispose of the shower cap. Rinse thoroughly with cool water and style as desired. Style Name:Peter Thomas Roth 24K Gold Pure Luxury Age-Defying Hair Mask & Bonnet System. Style Number: 5198290. Available in stores.
